Title: Image reader
Inventor: WADA SHINICHIRO
IPC: G06T1/00
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To provide an image reader capable of higher accurately measuring the read position of images with no error being generated, without generating a moire phenomenon. SOLUTION: The oblique lines of an oblique line pattern for which the plural oblique lines provided with an inclination of 45 deg. are arranged with equal pitches in the scanning direction of an original are read. A window W is set to the image data of a bit map (step S3), the centroid (pos) of the image data of the oblique lines present inside the window (W) is obtained (step S4), the window W is moved stepwise for each pixel in a main scanning direction, until the centroid pos enters the center part of the window W and a variable (s), which is the number of times of movement at the time is counted (step S5 and step S12 - step S14). A centroid Pi of the line in the main scanning direction of the image data is obtained at the respective positions in a sub-scanning direction in the image data (step S6).  Then, the differences at the different positions in the sub-scanning direction of the centroid Pi is converted into the actual read position of the image data (step S7).

Title: Fast atomic beam source
Inventor: KATO TAKAO
IPC: G21K1/00
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To generate a fast atomic beam with a very small beam diameter with good efficiency by neutralizing an ion beam of a very small size by metallic vapor in the inside of a neutralizing chamber. SOLUTION: A heater 1a of a liquid metal ion source 1 is heated and a metal ion beam 22 is emitted in the vacuum from the tip of the generated molten metal. A neutralizer 10 is so constructed that the beam axis of a beam 22 is adjusted with a d.c. electric field by an XY deflecting system 21 to be introduced into a neutralizing chamber 23 through an upper fine hole 28. The beam 22 comes into contact with the vapor of metal heated to a high temperature by a heater 26 to be neutralized without loss of energy and return to an atom. The atom having the large generated kinetic energy becomes a beam to be emitted from a lower fine hole 29 with a diameter of 0.5mm, and the mixed un-neutralized ion is removed by a deflecting system 24. Only the sub- micron focused fast atom beam 25 is emitted from a lower hole 30 with a diameter of 1mm of an ion removing cover. Accordingly, a fast atom beam with a diameter of 1μm or less can be generated with good efficiency.

Title: Method for recognizing character
Inventor: YOSHIDA HIROSHI
IPC: G06K9/72
Filed: 1987-12-22
Abstract: PURPOSE:To reduce the capacity of a word dictionary by substituting a character after a second character among the identical character for a repeat code when a word candidate character column continuously includes the identical character and only when the character is a repeat word formation character. CONSTITUTION:By a candidate character obtained by a character recognition part 11, the word candidate character column forming part 12 forms the word candidate character column. In this case, when this candidate character column repeatedly includes the repeat character, it is decided whether it is the repeat word formation character or not by referring a repeat word formation character table 18. When it is the repeat word formation character, the character after the second one among the identical character is substituted for the repeat code, an additional word candidate character column is formed and sent to a word collation part 15. On the other hand, when it is not the repeat word formation character, it is excluded from the word candidate character column.

Abstract: PURPOSE:To reduce the area of a chip by forming a plurality of reverse conductivity type resistance regions shaped onto the top face of a semiconductor layer and an oxide isolation layer, etc., being formed to at least one between the reverse conductiv ity types and deeper than the depth of the reverse conductivity type resistance regions and shortening distances among diffusion resistance regions. CONSTITUTION:n-type buried layers 7 are shaped to a p-type semiconductor substrate 8, and an n-type epitaxial layer 6 is formed. p-type diffusion resistance regions 5, 5' connected at a first terminal 1 and a fourth terminal 4 as external terminals are shaped onto the layer 6. An oxide isolation layer 10 is formed in depth deeper than the depth of the p-type diffusion resistance regions 5, 5' and not brought into contact with the p-type substrate in order to ensure electrostatic resistance in the lateral direction capable of preventing breakdown by static electricity applied between the first terminal and the fourth terminal 4. Consequently, an effective distance between the p-type diffusion resistance regions 5, 5' is lengthened only by the existence of the oxide isolation layer 10, and a distance between the p-type diffusion resistance regions 5, 5' required for obtaining specified electrostatic resistance can further be shortened. Accordingly, the area of a chip is reduced, and a semiconductor integrated circuit can be fined.
